Accurate Kinematic Trajectory Determination

The airborne mapping industry worldwide relies on GrafNav to produce accurate maps and DEMs, often in challenging

environments. These applications require reliability, high accuracy and rigorous quality control. Jobs over large

geographic areas can include long baselines, which have traditionally made accuracy requirements difficult to

achieve. GrafNav features such as multiple base station processing, tropospheric bias modelling and AdVance RTK

allow for precise accuracy for even the longest flights.

Differential GNSS provides excellent results, but base station setup can be problematic. Multiple features available

in GrafNav simplify differential operation. High elevation flights can often be affected by atmospheric error effects

that lead to poor elevation accuracy. GrafNav mitigates these errors using embedded advanced atmospheric

modelling. Base station coordinate errors can also cause problems. GrafNav’s Precise Point Positioning (PPP)

filter can be used to accurately verify or even solve the base station coordinates. PPP processing can also

be used in kinematic mode to eliminate the base station(s) from your workflow entirely. When used with

downloadable clock and orbit data the GrafNav PPP filter can provide accuracies of 5–30 cm for airborne data.

Receiver Independent Processing

GrafNav/GrafNet supports 28 different raw data formats, including RINEX, as worldwide users often employ

various types of GPS/GLONASS receivers. A flexible data conversion utility automatically detects most of

these formats. For those users without local base stations, the included download utility permits access to

several thousand continuously operating stations from networks such as CORS, IGS, IGN (France), GSI

(Japan), ARGN (Australia) and more.

Support for Special Applications

GrafNav/GrafNet can be provided as a developer’s kit that permits users to access the processing DLLs.

For a more simple software interface, GrafNav has an extensive number of command line functions that

makes it possible to completely automate processing. The GPS internet data download utility and the

raw data conversion utility also have command line options to enable automation of the entire process.
